Functions ¶
func In ¶
func In(r rune, ranges ...*unicode.RangeTable) bool
In reports whether the rune is a member of one of the ranges.
func Is ¶
func Is(rangeTab *unicode.RangeTable, r rune) bool
Is reports whether the rune is in the specified table of ranges.
func IsControl ¶
IsControl reports whether the rune is a control character. The C (Other) Unicode category includes more code points such as surrogates; use Is(C, r) to test for them.
func IsGraphic ¶
IsGraphic reports whether the rune is defined as a Graphic by Unicode. Such characters include letters, marks, numbers, punctuation, symbols, and spaces, from categories L, M, N, P, S, Zs.
func IsHan ¶
IsHan reports whether the rune is a Chinese characters.
Example ¶
package main
import (
"fmt"
"gopkg.in/goyy/goyy.v0/util/unicodes"
)
func main() {
fmt.Println(unicodes.IsHan('中'))
fmt.Println(unicodes.IsHan('文'))
fmt.Println(unicodes.IsHan('一'))
fmt.Println(unicodes.IsHan('a'))
fmt.Println(unicodes.IsHan('A'))
fmt.Println(unicodes.IsHan('1'))
fmt.Println(unicodes.IsHan(','))
fmt.Println(unicodes.IsHan(' '))
}
Output: true true true false false false false false
func IsOneOf ¶
func IsOneOf(ranges []*unicode.RangeTable, r rune) bool
IsOneOf reports whether the rune is a member of one of the ranges. The function "In" provides a nicer signature and should be used in preference to IsOneOf.
func IsPrint ¶
IsPrint reports whether the rune is defined as printable by Go. Such characters include letters, marks, numbers, punctuation, symbols, and the ASCII space character, from categories L, M, N, P, S and the ASCII space character. This categorization is the same as IsGraphic except that the only spacing character is ASCII space, U+0020.
func IsQuote ¶
IsQuote reports whether the rune is a quote. Returns true when the value of r is ' or " or `, otherwise it returns false.
Example ¶
package main
import (
"fmt"
"gopkg.in/goyy/goyy.v0/util/unicodes"
)
func main() {
fmt.Println(unicodes.IsQuote('"'))
fmt.Println(unicodes.IsQuote('`'))
fmt.Println(unicodes.IsQuote('\''))
fmt.Println(unicodes.IsQuote('a'))
fmt.Println(unicodes.IsQuote('1'))
fmt.Println(unicodes.IsQuote('A'))
fmt.Println(unicodes.IsQuote('一'))
fmt.Println(unicodes.IsQuote(' '))
}
Output: true true true false false false false false
func IsSpace ¶
IsSpace reports whether the rune is a space character as defined by Unicode's White Space property; in the Latin-1 space this is
'\t', '\n', '\v', '\f', '\r', ' ', U+0085 (NEL), U+00A0 (NBSP).
Other definitions of spacing characters are set by category Z and property Pattern_White_Space.
func SimpleFold ¶
SimpleFold iterates over Unicode code points equivalent under the Unicode-defined simple case folding. Among the code points equivalent to rune (including rune itself), SimpleFold returns the smallest rune > r if one exists, or else the smallest rune >= 0.
For example:
SimpleFold('A') = 'a'
SimpleFold('a') = 'A'
SimpleFold('K') = 'k'
SimpleFold('k') = '\u212A' (Kelvin symbol, K)
SimpleFold('\u212A') = 'K'
SimpleFold('1') = '1'
